Fermi Large Area Telescope observations of Local Group galaxies: Detection of M31 and search for M33
LAT collaboration
Cosmic rays (CRs) can be studied through the galaxy-wide gamma-ray emission that they generate when propagating in the interstellar medium. The comparison of the diffuse signals fr…
Multi-wavelength Observations of the Flaring Gamma-ray Blazar 3C 66A in 2008 October
LAT collaboration, A. A. Abdo et al., the VERITAS collaboration +4
The BL Lacertae object 3C 66A was detected in a flaring state by the Fermi Large Area Telescope (LAT) and VERITAS in 2008 October. In addition to these gamma-ray observations, F-GA…
Constraints on the Cosmic-Ray Density Gradient beyond the Solar Circle from Fermi gamma-ray Observations of the Third Galactic Quadrant
Fermi LAT Collaboration
We report an analysis of the interstellar -ray emission in the third Galactic quadrant measured by the {Fermi} Large Area Telescope. The window encompassing the Galactic plane f…
Fermi Large Area Telescope Observation of a Gamma-ray Source at the Position of Eta Carinae
The Fermi LAT collaboration
The Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope detected a gamma-ray source that is spatially consistent with the location of Eta Carinae. This source ha…
